I followed the instructions at https://www.youtube.com/watch?v=Tjip23g2c4w and now have a progress bar inside my navbar element, below the menu. Now because the progress bar is inside the navbar symbol, the bar itself is nicely copied to all other pages that have the navbar, but the interaction is not: it works on the homepage, but not on any other page (it just shows the bar at 100%).

How do I get the interaction to be included inside the symbol so it’s neatly copied over to the other instances of the navbar?
